Largest obstetrics/gynecology physician group practices

If you’re selling in the obstetrics or gynecology space, physician groups can be appealing targets for your marketing efforts because they tend to centralize their purchasing decisions, allowing you to profit from bulk sales and long-term partnerships through a single marketing connection.

Physician group size and specialty are two useful metrics for prioritizing physician group practices. By focusing on the largest physician groups within your target specialty, you can gain access to bigger sales opportunities and more relevant contacts.

How many obstetrics/gynecology physician group practices are there in the U.S.?

Our database shows that there are 4282 active obstetrics/gynecology physician group practices in the U.S. Because physician groups usually operate multiple locations, the number of physician group practices does not reflect the number of obstetrics/gynecology practices in the United States.

Why target obstetrics/gynecology physician groups?

Targeting a private practice doctor rather than a hospital or health system can offer easier access to key executives and decision-makers. Doctors working in large physician groups within your target specialty can be ideal points of contact for your marketing efforts.

Large obstetrics/gynecology physician groups require specialized technology, equipment, and training, and can present significant opportunities for sales and other valuable connections.

Tips for targeting obstetrics/gynecology physician groups

The challenges and priorities of each obstetrics/gynecology physician group are unique, so your marketing approach for each group should be unique, as well. Intelligence like tech install data, procedure and claims data, and Medicare charges can provide insights into the physician group that will allow you to personalize your outreach for maximum efficiency.

Focus on how your product, technology, or service can improve patient outcomes, enhance diagnostic capabilities, or optimize operations—whichever challenges are most pressing for the physician group. Be sure to include success stories from case studies or clinical trials that are relevant to their needs, too.
